Koide ratio exactly 2/3 from radial vortex excitations

Purpose

Phenomenological Koide fit using PDG lepton masses and a Z₃ phase ansatz (calibrated benchmark).

What it proves

The Koide relation $K = 2/3$ is reproduced when masses are anchored to PDG; useful baseline before eigenvalue derivation.

Relation to current theory

For the radial eigenvalue path without PDG mass fitting, see sim_75. The Standard Model treats lepton masses as 6 free Yukawas with no explanation for their near-perfect Koide value.

  Algebraic identity (exact):
    K = Σm / (Σ√m)² = 6a²/9a² = 0.6666666667

  Experimental Koide ratio:
    K_exp = 0.6666605115   (deviation from 2/3: 6.16e-06)

  K_SVT = 2/3 exactly       : PASS   (K = 0.6666666667)
  K_exp ≈ 2/3 (<0.1%)       : PASS   (K = 0.6666605115)
  Masses match experiment    : PASS
